Pete,

It looks as if the code is re-directing correcting
http://mydomain.com/test.php?id=1, but the code executes again when that
page loads.

the code:

substr($_SERVER['REQUEST_URI'], 0, $pos);

returns nothing the second time it called, thus re-directing again to
http://mydomain.com.


Try this as a fix:

<?php
if (strpos($_SERVER['REQUEST_URI'], "&"))
{
$new_url = "http://mydomain.com" . substr($_SERVER['REQUEST_URI'], 0,
strpos($_SERVER['REQUEST_URI'], "&"));
header("Location: $new_url");
}
echo substr($_SERVER['REQUEST_URI'], 0, strpos($_SERVER['REQUEST_URI'],
"&"));
?>
